ALLEN B. GOOKE, OF DANVILLE, ILLINOIS, ASSIGN'OR TO UNITED .A'U''IO(:rBAIl?HIC REGISTER 00., A CORPORATION OF ILLINOIS an'roenarnrc REGISTER vOriginal application filed February 16, 1931, Serial No. 516,198. Divided and this application filed July i 13, 1931. Seria1 1\1'o. 550,536.

This invention relates particularly to autographic registers of the type in which the duplicating strips are drawnfrom a suitable source of supply across a platen, upon 54 which tickets, orslips, are filled in and a record (original or copy) stored in the ma-- chine. r

The present application is a division 0 application Serial No. 516,198, filed February 16, 1931, and relates more particularly to a constantly operated feed mechanism which acts intermittently to feed flexible strips a determined distance.

The invention is applicable to various it kinds of'machines of the general character mentioned above. It may be used very advantageously in the type of machine having provision for storing the original slips and discharging the copies through a lat- 20 eral discharge orifice. It may be employed, also, in machines of the type where the original and a desired number of copies are discharged from the machine and the lowermost copy is stored in the machine.

In the embodiment shown in the accompanying drawings, the invention is applied to a side-delivery machine which extrudes the copies and retains the original.

In the drawings:

Fig. 1 isa longitudinal vertical sectional view of anautographic register embodying the invention; Fig. 2, a'broken transverse vertical sectional view on an enlarged scale of the feed-mechanisms, taken as indicated at line .22 of Fig. 1;Fig. 3, a broken transverse-vertical sectional view on an enlarged scale, showing one of the feed-mechanisms in a different position from that shown in Fig. 2; Fig. i, a broken longitudinal vertical sectional view, taken as indicated at line 4 of Fig. 2; Fig. 5, a similar view; takenas indicated at line 5 of Fig. 3-; Fig.6, a broken longitudinal elevational view of the mechanism for locking thecrank; and Fig. 7, a broken vertical sectional view taken as indicated at line 7 of Fig. 6. a

In the embodiment illustrated, A designates a casing, or frame, provided with a supply compartment A, a platenA a cover A adapted to partially inclose the platen,

a filing compartment A and a closure A affording an entrance to the compartment A; B, main feed-mechanism for drawing the duplicating strips from the supply compartment over the platen A C, clamping and cutting mechanism adapted to hold and sever the record strip; D, auxiliary feedmechanism for projecting the record copy into the filing compartment A; E, a laterally-open delivery chute through which the copy-strips are delivered; and F, a lock for the closure A The casing A is of known construction.

The platen A and the cover A are pivotally connected at one lateral edge with the upper portion of aside wall of the casing, in the usual manner. The closure A is connected at the bottom edge with the lower front end portion of the casing by a transverse pivot 1. The base-portions of the compartments A and A are inclined downwardlyand rearwardly to reduce the required head space and-to provide adownwardly extending slide in the compartment A for the record slips.

The feed-mechanism B is similar to that described in the Jensen application, Serial No. 289,821, filed July 2, 1928, and comprises an upper feed-roll 2, and a lower feed-roll 3, which have intermeshing gears 4 and 5. The feed-rolls are provided with normal feeddisks 2 and 8 and with initial feed segments 2 and 3 The upper feed-roll is mounted in a transverse housing 6, one end of which is pivotally supported at 7 .and the otherv end is equipped with a releasable catch 8. The feed-rolls are driven by the crank-shaft 9, through the medium of gears, as will be explained more fully below. The shaft 9 is equipped with a-crank 9 which co-operates with a latch-device or withdrawable stop 10, shown in Figs. 6 and 7.

The cutter-mechanism C is shown with a clamping bar 11 and a cutter-blade 11 This mechanism, also, is similar to that shown in Jensen application Serial No. 289,821.

In the cycle of operations of the machine, the main feed-mechanism B feeds the strips a form-length and the strips then remain at rest untilthe severing and filing are effected.

The auxiliary feed-mechanism D, accordingly, is designed to effect feeding of the severed slips, seriatim, at proper intervals,

i. e., after severance of the slips.

Themechanismil) comprises apa-ir 02f eontinuously rotating d-ifi'erential *feed-rol ls 12 and 13, provided with suitable trunnions 12 and 13*, respectively, Apairof journal members 14, mounted on the slide-walls of the .casing A, are provided with elongated slots 14, which serve as ournals for the tryrnnionsond permit a certain amount of relative movement between the rolls. The louver portions -.oif theslots are equipped with springs 15=aind plimg ers 15*, which .yielclingl y support the roll 13 in its uppermost osi'tion. The rolls are also provided with cdlgars 12 and 11'3", whic'hserve to'keep the rolls in proper spaced relation.

The feed rollls 1-2'a nd 13 are provided with upraised spirals or threads 12 and 13, re specti-vel y,andthethreads 12 are .of the same length as threads 13- ;but have less pitch and a smaller effective diameter (the diameter of the thread measured at its periphery). The

' threads are positioned so that when the rolls are rotated in opposite directions, atthe same peripheral or surface .speed, they will intermiittently .come into 0 posed relationship "for one complete thread ength and will exert a gripping and feeding action upon an interposed web, as illustrated in Figs. 2 and 4. When the threads ,are not directly opposed no gripping action is obtained as the paper will flex and the threads will slip over the paper as shown in Figs.3 and 'Whijle in the present embodiment each roll is shown with a right and left single thread, obviously more groups of threads and mul tip'le threads may be used without departing frOm the spirit of the invention.

. The crank shaft 9 is provided with a gear 16 which meshes with and drives .a larger gear 1? ofthe cutter mechanism which in turn drives both of the feed-mechanisms B and D. The lower feed roll '3 of the main feedinec'hanisrn B ,is provided with a pinion 1,8 whichmeshes with and is driveniby the gear 1.7. The shaft 12 of the auxiliary feed-mechanism D projects through the journal 1e and easing A. and provides a pivot for an idler gear 19 which'is driven the gear 17 and which inturn drives the pinion 20 mounted on the lower shaft13. The shafts 1 3 and 12 are provided withv intermeshing gears 21 and '22, which serve to rotate the spiralson the shafts at a uniform peripheral speedL. Y r

The Crank 9?, as shownin '6 and7,

has .a'slot 23 end portion to engage the A latch 10 on every second revolution. The

cra-nk-shaft19is provided witha pinion '24 which meshes with ,and drives a cam-gear 25', which is pivotallygmounted on thecasing and 'depressesa plunger 10 which presses the latch 10 out .ofthe "path of the crank on its first revolution, as wil-l'be readily understood from the drawings. A spring 26 is provided to keep the plunger 10 in contact with the cam.

A pair of curved guide plates 27 and 28 are proyidedito direct the strip v{from the cutter .Inedhanism C :to the teed-mechanism D. .Asnaall tranverse shelf 29 is attached to the casing wall 110 directthe slips from the rolls to a proper position in the compartment A". If desired, the shelf may be pivoted at the .edgeneanest the feed roll and a cam-actuated arm provided to swing the shelf at proper times to .assist in filing several slips.

nGambon strips (not shown) may be fed over the platen between the strips in any suitable manner- As shown in Fig. '1, a bardi) extends across the upper porti on of the casing immediately back of the platen, just below the meeting place .of the food-11101192 :and The bar is slotted to accommodate the lower feed-disks and provides a tear-off edge 30 on whidh copy may be severed from the lower strip of paper. Register pins 31 :are provided to (engage perforations :with which thepaiperstrips are provided, and thereby assist in positioning the strips, initially, .oner the platen.

To operate the machine, after the slips have been filled in, (the latch lit) is depressed and \the crank 9 rotated two complete :re olutions, that is, until stopped by the latch During this operation the lower strip 212 is drawuuoyerzthe .platenand projected domwardly thnongh the chute and the uppe strip designated $313 is projected iby the main feed mechanism B under the cutter :blade 1.1 down through the guides 2.7 and :28 to the auxiliary feed mechanism D. When the register perforations in the strips reach the teed disks at B the feeding will stop and the elamping bar 11 will loo lowered and grip the upper strip while the blade 11 zdeseends and severs the slip. Just prior tojvhe complete seyeranee of the slir the spirals ion rolls 12 and '13 will come into opposed relation and draw the slip away from the bladedown into thelcompartrnent A.

Thus, it will he understood that the feed rolls of .the auxiliary feed mechanism are continuously actuated and provided with deferred action -slip-.grippinmeans.

'Dhe foregoing details descniiption has ative relation.
